Energy Efficient Hybrid Precoder for Cell-Free Wideband mmWave Massive MIMO Systems

In a cell-free (CF) wideband millimeter-wave (mmWave) massive multiple-input multiple-output (mMIMO) system, a small number of users are simultaneously served by a much larger number of distributed access points (APs). These APs employ hybrid precoders to achieve beamforming gain. However, the beam...
